  7. Abstract:
  8. This study has been carried out for investigating the need for an appropriate and fast seismic analysis method to be applied in performance based design (PBD), and show the application of Endurance Time (ET) method and its advantages in PBD. The major goal of this project is analysis and study of behavior of concrete frames with retrofitted shear walls with FRP by ET method with acceleration functions which are compatible with actual earthquake and comparation with time history analysis, forand comparation of whole results with shear wall frames that are not retrofitted. Performance criteria of FEMA code were used fore comparation of two frame categories (retrofitted and not retrofitted). The accuracy of models was tested by comparation of precise results of ANSYS model with results of PERFORM3D model. The models in these analyses were three frame categories with 5, 9 and 13 stories and 5 spans that centeral spans of them have shear wall. After confidence from accuracy of models, time historically nonlinear analyses for seven actual earthquake accelerographs and three ET acceleration functions which are compatible with spectrum of average of seven actual earthquake accelerographs were done. Whole of results for three frame categories were extracted and results of seven actual earthquake accelerographs and three ET acceleration functions were compared. Furthermore, improvement of behavior of frames was checked by comparation of retrofitted and not retrofitted frames. The results of three ET acceleration functions were good approximation of seven actual earthquake accelerographs. Moreover, the performance of shear wall frames after retrofition was improved.
